Description
Technical field
This utility model belongs to coating equipment technical field, and in particular to intelligent self-cleaning washes double solidification finishing systems.
Background technology
Spray Polyurea Elastomer（Spray Polyurea Elastomer, abbreviation SPUA）Technology is external to adapt to environmental protection
Demand and a kind of new " omnipotent " application techniques for researching and developing, are described as the late 20th century coating, application techniques field
Greatest invention.The raw material of SPUA coating is divided into two groups：Isocyanate ester compound and aminated compoundss, both can be in nothing
Quickly reacted in the case of catalyst, formed fine and close, continuous, seamless, tough elastomer coating.The coating has excellent
Different physical property and decay resistance, can be used for field of corrosion prevention, suffer from the construction of various Large Infrastructure Projects
Huge application prospect.The technology applies more than 20 years in developed countries such as North Americas, and the market demand is very powerful.
20th century the mid-80, the Dudley J. Primeaux II of Texaco companies and its team are based on reaction note
Penetrate molding（RIM）Technology, has invented SPUA technologies in Austin laboratorys, and has delivered research article earliest in 1989
（Primeaux, D J. Spray Polyurea-Versatile High Performance Elastomer for the
Polyurethane Industry [A] // 1989, Polyurethanes ’89, the 32nd Technical/
Marketing Conference [C], SPI, San Francisco, CA, pp. 126-130.）.Subsequently, the U.S.
GUSMER companies（By GRACO corporate buyouts）The polyureas flush coater of development causes the technology to realize commercialization.At present, it is beautiful

It is by sliding that spray gun controls the mixing and ejection of two kinds of raw materials, i.e. charging aperture with the connection and cut out of hybrid chamber using spanner
Come what is realized, spring compression is only leaned in sealing.In this case, it is difficult to ensure that closed under high pressure, easily make in operation
Into the leakage of raw material.And two kinds of component raw materials once contact just solidify immediately, the response time be less than 10 seconds, once therefore leak,
It is easy to will result in the blocking of spray chamber, is that construction is made troubles.3. cavity internal pressure easily produces fluctuation and causes component to be mixed
Close the uniformity impacted, mixed proportion produces change, therefore the shallow layer effect of the technique application is poor.4. due to two kinds of raw materials
Viscosity it is different, the feed rate under thus like pressure is different, causes mixed proportion to slightly have difference.5. the technique belongs to fast
Fast reactive spray system, the control requirement to reaction condition are very high, also include temperature control system, therefore grasp in existing equipment
Make comparisons complexity, the difficulty of even spread is very big.Based on these problems, SPUA technologies are in construction, professional except adopting
Beyond equipment, it is necessary to operated by the workmen for possessing professional technique.Which limits the extensive of SPUA technologies
Promotion and application.
The domestic exploratory development to spraying elastomeric technology starts from nineteen ninety-five, and researches and develops successfully to have after 3 years and independently know
Know the polyurea formulation system of property right and apply for multinomial patent of invention.Hereafter, domestic scholars are also carried out with preparation to polyureas synthesis
Numerous studies have simultaneously delivered related ends, but China also focuses primarily upon the compounding of polyureas in the research that polyureas sprays elastomer
